New efficient sulfurizing reagents for the preparation of oligodeoxyribonucleotide phosphorothioate analogues. (1/1)

A set of new sulfurizing agents representing disulfides of arylsulfonic acids has been developed for the automated synthesis of phosphorothioate oligonucleotide analogues via the phosphoramidite method. These reagents, such as bis(benzenesulfonyl)disulfide, bis(p-toluenesulfonyl)disulfide, bis(p-methoxybenzensulfonyl)disulfide, and bis (p-chlorobenzenesulfonyl) disulfide, are easily prepared crystalline solid compounds. They are relatively inexpensive, easy to handle, and efficiently convert internucleotide cyanoethyl phosphite to the phosphorothioate triester within 1-2 min. The efficiency of phosphorothioate oligonucleotide synthesis with the use of these reagents is comparable to that of phosphodiester oligonucleotides.  (+info)

During the allergic reaction mucosal T cells are activated and a local increase in numbers occurs. In peripheral blood, a concomitant T cell activation and switch towards memory phenotype appears. E-selectin, intercellular adhesion molecule (ICAM)-1 and vascular cell adhesion molecule (VCAM)-1 were studied in nasal mucosal biopsies taken during a time-course provocation study, including patients with seasonal allergic rhinitis and healthy controls. Allergic patients were also studied during the natural pollen season with particular attention to the influence of local corticosteroid treatment. Before provocation allergic patients and controls did not differ concerning the expression of endothelial adhesion molecules. However, the epithelial ICAM-1 expression was increased among allergics (P , 0.05). Repetitive allergen provocation induces an increased endothelial expression of VCAM-1 in allergic patients (P , 0.01). Similarly, VCAM-1 expression was increased during the natural pollen season (P , ...
